Triangles RDO and RHC are similar, so you have
.. RO:RC = RD:RH
.. RO:(RD +CD) = RD:(RO +OH)
.. 6:(4 +CD) = 4:(6 +4) . . . . . . . fill in numbers
.. 6*10 = 4(4 +CD) . . . . . . . . . . product of means = product of extremes
.. 15 = 4 +CD
.. CD = 11
Answer:
The answer is A. A+C because Rational numbers can be made by dividing two integers. integers are whole numbers a number that is not a fraction.
You would just do 1÷5 so it would equal 20 or 20%.
